Management experience of brain metastasis after liver transplantation for hepatocellular carcinoma / 中华器官移植杂志

Objective:To explore the pathogenesis and prognostic factors of brain metastasis of hepatocellular carcinoma(HCC)after liver transplantation(LT).Methods:Retrospective review was performed for 17 HCC cases with brain metastasis after liver transplantation from 2000 to 2020.All cases were diagnosed as hepatitis B cirrhosis complicated with HCC.All of them were beyond the Milan Criteria.The immunosuppressive regimen consisted of baliximab + mycophenolate mofetil + calcineurin inhibitors(CNIs)+ corticosteroids in early postoperative period with a gradual tapering of corticosteroids and mycophenolate mofetil.Three patients received sirolimus immunotherapy after tumor recurrence and withdrew CNIs.One of three cases received sorafenib.Results:Other organ involvements included lung metastasis( n=16, 94.1%), bone metastasis( n=5, 29.4%)and liver metastasis( n=6, 35.3%). The median survival time after brain metastasis was 7 months and the 1-year cumulative survival rate 29.4%.The median survival time post-LT was 14 months and the 1-year cumulative survival rate 64.7%.Among 7 patients with a resection of brain metastasis, two deaths at Month 1 post-operation were due to cerebral hemorrhage.The longest survival time was 214 months and the median survival time 9 months. Conclusions:The prognosis of brain metastasis post-LT remains poor.However, early detection and reasonable treatment can prolong patient survival time and even achieve long-term survival.Most brain metastases are accompanied by lung metastases.And the finding of lung metastatic tumor hints at a presence of intracranial lesions.

OShnscc: a novel user-friendly online survival analysis tool for head and neck squamous cell carcinoma based on RNA expression profiles and long-term survival information / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Head and neck squamous cell carcinoma (HNSCC), as the most common type (>90%) of head and neck cancer, includes various epithelial malignancies that arise in the nasal cavity, oral cavity, pharynx, and larynx. In 2020, approximately 878 ‍ 000 new cases and 444 000 deaths linked to HNSCC occurred worldwide (Sung et al., 2021). Due to the associated frequent recurrence and metastasis, HNSCC patients have poor prognosis with a five-year survival rate of 40%-50% (Jou and Hess, 2017). Therefore, novel prognostic biomarkers need to be developed to identify high-risk HNSCC patients and improve their disease outcomes.

The effect of age and abstinence time on semen quality: a retrospective study / 亚洲男科学杂志(英文版)

This study analyzed the effects of male age and abstinence time on semen quality and explored the best abstinence time for Chinese males among different age groups. Semen parameters, including sperm kinetics, morphology, and DNA fragmentation index (DFI), were reviewed from 2952 men. Samples were divided into six age groups (≤25 years, 26-30 years, 31-35 years, 36-40 years, 41-45 years, and >45 years) and were divided into six groups according to different abstinence time (2 days, 3 days, 4 days, 5 days, 6 days, and 7 days). The differences in semen quality between the groups were compared, and the effect of age and abstinence time on semen quality was analyzed. Significant differences were observed in semen volume, progressive motility (PR), and DFI among the age groups (all P < 0.05), and no significant differences were observed in sperm morphological parameters (all P > 0.05). There were significant differences in semen volume, PR, and DFI among different abstinence time groups (all P < 0.05) and no significant differences in sperm morphological parameters (all P > 0.05). Pearson analysis showed that male age and abstinence time were both significantly correlated with sperm kinetics and DFI (both P < 0.05), while no significant correlation was found with sperm morphological parameters (all P > 0.05). The box plots and histograms of men's age, abstinence time, and semen quality show that most semen quality parameters differ significantly between the 2 days and 7 days abstinence groups and other groups at different ages. Except for the sperm morphology parameters, sperm kinetic parameters and sperm DFI are linearly related to male age and abstinence time.

Objective:To understand the current situation of male nurses in Dalian area and explore its future development direction.Methods:From August to September in 2020, 189 male nurses who had been engaged in clinical nursing for more than one year in 29 hospitals in Dalian were selected by convenient sampling method, and they were investigated by questionnaire. SPSS 25.0 software was used for statistical analysis. The counting data were described by rate or constituent ratio. Logistic regression analysis was used to analyze the important factors influencing male nurses′ willingness to change profession.Results:A total of 189 male nurses were investigated, 137 of them were under 30 years old, accounting for 72.5%. They had high education background and low professional title, mainly concentrated in ICU, operation room and emergency department of public owned 3A or 3B hospitals, with a monthly income of 3 000 to 8 000 yuan. 33 nurses(17.5%) chose nursing profession because they couldn′t change careers by profession adjustment. 135 nurses (71.4%) considered that work pressure was high. 70 nurses (37.0%) had the idea of changing careers. The main influencing factors included:nursing career was not in accordance with individual interest, dislike of female boss, low income. The prominent problem in nursing career was "inconvenience in gender""the confusion of self-positioning".Conclusions:The hospital should improve the income of male nurses, reduce the work pressure, establish magnetic hospital, establish career planning for them, and expand the team of male nurses. Male nurses should take the initiative to improve their professional ability and professional title, so as to provide necessary conditions for the realization of nursing managers, educators, researchers and other professional goals.

Characteristic manifestations of ΔCT in hepatitis B cirrhosis with upper gastrointestinal bleeding and establishment of a predictive model / 临床肝胆病杂志

Objective To investigate the CT characteristics of hepatitis B cirrhosis, and to predict the risk of bleeding by establishing a predictive model for upper gastrointestinal bleeding in liver cirrhosis. Methods A retrospective analysis was performed for the clinical data of 101 patients with hepatitis B cirrhosis who were admitted to Tianjin First Central Hospital from January 2015 to June 2021, and these patients were divided into upper gastrointestinal bleeding group and non- bleeding group. The two groups were compared in terms of laboratory findings and CT values in plain scan, arterial phase, portal vein phase, and venous phase measured by contrast-enhanced CT, and the changes in CT values (ΔCT) across different phases were calculated. The t -test or the Mann-Whitney U rank sum test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. Logistic regression analysis was used to predict the related risk factors; The discrimination of the model was evaluated by calculating the area under the working characteristic curve of the subjects, and the model calibration criteria were determined by Hosmer-lemeshow. Based on the results of multivariate logistic regression analysis, Rstudio4.1.2 R package was used to establish a predictive model, and draws the corresponding ROC curve, calibration curve and clinical decision curve. Results There were significant differences in serum TBil, WBC and PLT levels between the non-bleeding group and the bleeding group (all P < 0.05). There were significant differences in liver-plain, spleen-P-plain and spleen-P-A ΔCT(all P < 0.05). The univariate logistic analysis showed that there were significant differences in leukocytes (odds ratio [ OR ]=0.770, 95% confidence interval [ CI ]: 0.624-0.952, P =0.016), platelets ( OR =0.979, 95% CI : 0.965-0.994, P =0.006), liver plain scan ( OR =1.142, 95% CI : 1.058-1.233, P =0.001), ΔCT value of the spleen from portal vein phase to plain scan ( OR =0.979, 95% CI : 0.959-1.000, P =0.050), and ΔCT value of the spleen from portal vein phase to arterial phase ( OR =0.979, 95% CI : 0.944-0.994, P =0.015) between the hepatitis B cirrhosis patients with upper gastrointestinal bleeding and those without bleeding. The multivariate logistic analysis showed that platelets ( OR =0.968, 95% CI : 0.944-0.993, P =0.011), liver plain phase ( OR =1.148, 95% CI : 1.047-1.259, P =0.003), and ΔCT value of the spleen from portal vein phase to arterial phase ( OR =0.951, 95% CI : 0.908-0.995, P =0.030) were independent risk factors for upper gastrointestinal bleeding. A predictive model for upper gastrointestinal bleeding in hepatitis B cirrhosis was established based on the results of the multivariate logistic analysis, and a calibration curve was plotted. This model had an area under the receiver operating characteristic curve of 0.801 at the cut-off value of 0.433, with a sensitivity of 81.4% and a specificity of 77.6%. The calibration curve of the model fitted well with the ideal curve. Conclusion There are special ΔCT changes in hepatitis B cirrhosis, and the predictive model based on ΔCT has a good predictive ability for upper gastrointestinal bleeding in patients with hepatitis B cirrhosis.

Evaluation of the effect of remote lifestyle intervention on the management of weight and related indicators in the overweight and obese population / 中华健康管理学杂志

Objective:To evaluate the effect of remote lifestyle intervention on the management of weight and related indicators in the overweight and obese population.Methods:A total of 400 individuals with overweight or obesity who participated in remote lifestyle intervention in the Health Management Department of Shenzhen People′s Hospital from May 2015 to December 2018 were included as the remote intervention group, and 400 individuals with overweight and obesity who matched their age and gender were selected as the control group. Dietician established individual WeChat groups with the remote intervention group, and the WeChat platform was used to conduct remote lifestyle intervention for them, including setting weight control goals, giving timely feedback to the food log based on photos, providing exercise guidance and psychological support. The control group received personalized diet and exercise prescriptions, but did not receive remote intervention. After adjusting the data by propensity score matching method, univariate and multivariate logistic regression models were used to analyze the management effect of weight and related indicators in the two groups after one year.Results:After one year of intervention, effective data were obtained from a total of 755 cases (371 cases in the remote intervention group and 384 cases in the control group), and effective data were retained from 446 cases (223 cases in the remote intervention group and 223 cases in the control group) after bias matching. The body mass index (BMI), systolic blood pressure, fasting blood glucose, triglyceride, total cholesterol, low-density lipoprotein, and serum uric acid of the remote intervention group [(24.85±2.52) kg/m 2, (110.21±10.53) mmHg, (4.96±0.65) mmol/L, (1.25±0.82) mmol/L, (4.87±1.11) mmol/L, (2.88±0.74) mmol/L, and (306.01±95.66) mmol/L respectively] were significantly lower than that of the control group [(27.76±2.28) kg/m 2, (121.14±14.07) mmHg, (5.10±0.87) mmol/L, (1.54±0.83) mmol/L, (5.28±0.96) mmol/L, (3.13±0.80) mmol/L, (355.16±92.68) mmol/L respectively] (all P<0.05). After intervention, intervention was consistently being influencing factors when BMI was reduced by 4%―12%, ( P<0.05). The probability of a 12% reduction in BMI in the remote intervention group was 112.486 times higher than that in the control group (95% CI: 16.852-890.266). At the same time, the initial BMI was an influential factor for the restoration of normal BMI. For every 1 kg/m 2 decrease in the initial BMI, the probability of restoration of normal BMI was 4.76 times higher than that before the decrease (95% CI: 3.222-5.057). Conclusions:Remote lifestyle intervention has a certain effect on the management of weight and related indicators in the overweight and obese populations. It has significant effect on weight loss of overweight and mildly obese people, but has limited effect on moderate and severe obese people.
